MILK-BOTTLE RETAINER.

Specification of Letters Patent.

Patented Nov. 14, 1916.

Application filed July 28, 1916. Serial No. 111,904.

To all whom it may concern Be it known that I, JOSEPH PETRovrroH, asubject of the Czar of Russia, and a resident of the city of Toronto, inthe county of York, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in Milk-Bottle Retainers, of whichthe following is the specification.

My invention relates to improvements in milk bottle retainers and theobject of the invention is to' devise a simple means whereby a milkbottle, when left at the door of a consumer, can be locked in positionby the milk man so as to prevent its removal by any unauthorized personand it consists essentially of the following arrangement andconstruction of parts hereinafter more particularly explained by thefollowing specification.

Figure 1, is a general perspective view of my device shown in the openposition. Fig. 2, is a similar view to Fig. 1 showing my device in thelocked position with the upper portion of the milk bottle shown inposition so as to be secured thereby. Fig. 3, is a plan view of mydevice with the top cover plate removed and corresponding to theposition shown in Fig. 1. Fig. 4, is a similar view to Fig. 3 showing mydevice in the closed position. Fig. 5, is a sectional view on line m-Fig. 3. Fig. 6. is a sectional view on line m' 1 Fig. 3. Fig. 7, is asectional view on line w y Fig. 3. Fig. 8,

is a perspective detail of the slide piece.

In the drawings like letters of reference indicate corresponding partsin. each figure. 1 indicates a bracket provided with upper v and lowerlug portions 2 and 3 through which orifices 2" and 3 extend throughwhich screws or other suitable securing devices are screwed into a wallor door or other suitable support on which my device is designed to besecured.

4 indicates a casing extending outwardly from the center portion of thebracket 1 and comprising upper and lower plates 4* and 4 and side wallportions 5 and 6 separating the upper and lower plates 1* and 1 so as toform the hollow interior of the casing.

7 indicates a fork extending forwardly from the casing and preferablyformed in tegral with the lower plate 4. i

4 and 4 indicate longitudinal grooves formed in the inner faces of lowerplates 4* and 4.

8 indicates a slide piece fitting in the grooves 4 and 4 so as to beslidable therein. The body of the slide piece 8 is provided with a jawportion formed by the members 8 and 8', the jaw being provided at itsbase with a V-shaped portion 8 8 indicates a cross head secured betweenthe jaw members 8 and 8 at their ends.

8 indicates a teat extending inwardly from the end of the slide piece 8,and 8 indicates a teat opposing'the teat 8 and extending from the innerend of the hollow casing 4.

9 indicates a compression spring extending between the inner end of theslide piece 8 and the opposing wall of the casing 4 and into which theteats 8 and 8 extend.

One end of the cross head 8 is provided with a projecting portion 8having an inclined lower face 8 10 indicates a block secured inside thecasing against the back wall thereof.

11 indicates a vertical pin extending through the block 10 and at itslower end into the bottom plate 4: of the casing 4.

12 indicates a swingable piece having an orifice 12 through which thepin 11 freely extends. The free end of the piece 12 is designed to swingup and down in a vertical plane.

13 indicates a compression spring fitting the upper and into an orifice13 formed in the lower plate 4' of the casing and bearing at its upperend against the lower face of the piece 12. The upper-face of. the piece12 is provided with an inclined upper face portion 1 10pposing theinclined face 8 of the cross head 8 when the device is in the openposition.

15 indicatesa recess formed in the swing-v is designed to extend throughthe notch and i groove 17 so that the bit of the key, when the key is inposition, fits into the areshaped notch 17 and the shank of the key inthe groove 18.

20 and 21 indicate a pair of semi-circular arms pivoted at 22 and 23 tothe upper and lower plates 1* and at of the casing a. The

; inner ends of the arms 20 and 21 are proscribe the operation'of thesame.

When inserting the bottle in the device so as to secure it in positionagainst removal all that it is necessary to do is to insert the neck ofthe'bottle in the fork 7 with the enlarged rim ofthe bottle above thearms 20 and 21. In this position the bottle is forced inwardly againstthe end of the slide piece 8 forcing it inwardly against the compressionof the spring 9, such inward movement being continued until the crosshead 8 is carried far enough inward to carry the inclined lower face 8of the portion 8 past the inclined face 14, the piece yielding dur-' ingthis operation against the pressure of the spring 13. As soon as theinclined face 8 has passed the inclined face 14 the piece 12 swingsupwardly sothat the forward edge of the portion 8 engagesa'gainst theshoulder 14?. During this operation the V-shaped portion 8 of the slidepiece 8 forces the inner ends of the arms 20 and 21 formed by theportions 24 and 25 outwardly and the opposite ends of the arms 20 and 21inwardly together into the position shown in Fig. 4:. When the arms 20and 21 have reached this position they are locked in place by theengagement of the portion 8 with the shoulder 14* as hereinbeforedescribed.

When the purchaser of the milk desires to remove the bottle from theholder all that he has to do is to insert a key into the notch 16 andturn the head ofthe key inthe' recess 17 so that the bit engages withthe free end of the piece 12 depressing it against the compression sring 13 and thereby carrying the shoulder 12 below the portion 8 By thismeans the cross head 8 is freed and the cross head and slide piece 8,which are formed integral, are carried forwardly in the grooves 1 and 4As the cross head 83 passes forwardly it strikes the arc-shaped ends ofthe arms 20 and 21 there by spreading the arms apart into the positionshown in Fig. 3. The bottle can then be removed. The key is, of course,then removed by the purchaser of the milk bottle and retained by thepurchaser.

. From this desenp'aea it win be seen that I have devised a very simpledevice for retaining milk bottles in place when they are left at thedoor of purchaser so as to prevent their removal by any unauthorizederson.

l13.l I claim as my invention is:

1. A milk bottle retainer comprising a main supporting bracket, a pairof pivoted arms designed to surround the neck ofthe milk bottle, alongitudinally movable bar slidably held in the bracket between thearms, a compressionspring normally holding the bar in its outwardposition, an engaging mcmber carried by'the longitudinally movable barand a coacting spring pressed engaging member swingably mounted on thebracket and designed to engage with the engaging member of the bar whenthe bar is moved rearwardly.
